/**
* An asynchronous channel for stream-oriented listening sockets.
*
* <p> An asynchronous server-socket channel is created by invoking the
* {@link #open open} method of this class.
* A newly-created asynchronous server-socket channel is open but not yet bound.
* It can be bound to a local address and configured to listen for connections
* by invoking the {@link #bind(SocketAddress,int) bind} method. Once bound,
* the {@link #accept(Object,CompletionHandler) accept} method
* is used to initiate the accepting of connections to the channel's socket.
* An attempt to invoke the <tt>accept</tt> method on an unbound channel will
* cause a {@link NotYetBoundException} to be thrown.
*
* <p> Channels of this type are safe for use by multiple concurrent threads
* though at most one accept operation can be outstanding at any time.
* If a thread initiates an accept operation before a previous accept operation
* has completed then an {@link AcceptPendingException} will be thrown.
*
* <p> Socket options are configured using the {@link #setOption(SocketOption,Object)
* setOption} method. Channels of this type support the following options:
* <blockquote>
* <table border summary="Socket options">
* <tr>
* <th>Option Name</th>
* <th>Description</th>
* </tr>
* <tr>
* <td> {@link java.net.StandardSocketOptions#SO_RCVBUF SO_RCVBUF} </td>
* <td> The size of the socket receive buffer </td>
* </tr>
* <tr>
* <td> {@link java.net.StandardSocketOptions#SO_REUSEADDR SO_REUSEADDR} </td>
* <td> Re-use address </td>
* </tr>
* </table>
* </blockquote>
* Additional (implementation specific) options may also be supported.
*
* <p> <b>Usage Example:</b>
* <pre>
* final AsynchronousServerSocketChannel listener =
* AsynchronousServerSocketChannel.open().bind(new InetSocketAddress(5000));
*
* listener.accept(null, new CompletionHandler<AsynchronousSocketChannel,Void>() {
* public void completed(AsynchronousSocketChannel ch, Void att) {
* // accept the next connection
* listener.accept(null, this);
*
* // handle this connection
* handle(ch);
* }
* public void failed(Throwable exc, Void att) {
* ...
* }
* });
* </pre>
